To'all whom "it may concern..-

Be it known that I, FREDERICK H. AI.L- ING, a citizen of the United States, residing in New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful improvements in Clutches for Reliefographs, oi which the following is a specification.

This invention pertains to clutch mechanism where it is necessary to cause a constantly rotating member toengage another rotatable member and cause them to rotate in unison for one revolution, and thereupon to automatically disengage, notwithstanding the fact that the operative member that caused the engagement of the members, is

not retracted upon the completion of the anism, which mechanism is actuated from the means used to position the mating dies.

One of the objects of the assent invention is to p'roducea form of clutch mechanism that will cause but a single reciprocation of the die members, and hence but a single revolution of the rotary driving member In the accompanying drawings is shown one embodiment of my invention, and certain portions of a machine for producing printing surfaces, similar to that set forth in said patent to Crane.

Figure 1 is a side elevation olsuch mech anism, certain parts being shown in section. Fig. 2 is an end view of one of the clutch members. Fig. 2) is a section through the clutch member on the line 3--3 indicated in Fig. 2. Fig. 4 is a section through certain parts of the clutch member shown in Fig. 2, taken on the line. l-1 indicated therein. Fig. 5 is a view similar to Fig. 4 showing the parts in different positions. Fig. 6 is an end elevation of the parts shown in Figs. 4 and 5. Fig. 7 is a separate view of the trip lever.

This ro- Fig. 8 is a'view of the arm carryin the trip lever. Fig. 9 is a separate View 0? the cam lever for shifting the locking awl. Fig. 10 is an end view of the spring c utch'meniber. Fig. 11 is a side elevation of the complete machine, showing the means for operating the printing means, actuated by the eccentrics; and Figs. 12 and 13 show the sleeves having inclined surfaces for operating one clutchmcmber.

In the mechanism shown in Fig. 1, the key levers K, corresponding to characters on the type wheels that are mounted on shafts A and B, when shifted, serve to stop constantly rotating type wheels (not shown) with the desired characters oposite. The shafts A and B are connected or rotation in unison by equal gears a and l). The shaft A carrying the gear a is rotated by a shaft member 9 carrying a friction clutch member 10.

The clutchmember engages with a clutch rim 1'1 oi a clutch member denoted generally by 12, and which is constantly rotated by any suitable means, such as a belt 8. On the shaft A, is an arm. 13 carrying a lug 14. In the .path of movement of the lug 14, are a circular series of stop pins 15 carried by supporting plates 16 and 17, being endwise movable therein, and connected with the levers K, whereby the depression of a key lever will shift the stop pin connected therewith, moving its extremity into the path of movement of the lug 14. The movement of the stop arm 13 is thereby arrested, and the snafts A and B are stopped, positioning the die wheels with the character corresponding to the hey lever in painting position. The described arrangement of key levers, stop pins, geared printing members, and the stop arm cooperating with the stop pins, is simi lar to that shown in the said patent to Crane. Upon the arresting oi" the shafts A and B of the printing members, means are shoivn in Fig. 11 for bringing them together, which are operated by connecting rods reciprocated by wrist pins on the driving shaft. In the present invention, the said means are constituted by wrist pins 18 and 19 that are connected with the clutch member 12'constantly driven from the belt 8.

in the Crane patent, a friction clutch de vice is used for normally rotating the printingmcmbers, whereby, upon the members being arrested through the key levers-and stops, the driving member of the clutch will continue its rotation, and immediately upon the printing member being released from the stop mechanism, its rotation Wlll continue,

' for the purpose of permitting arrest of the printing members in different positions. In the present invention, the clutch member 10 secured to the shaft member 9 is composed of {a cross arm 21 of resilient material, carrying Zliametrally opposite friction blocks 22 that are pressed tightly against the friction rim 11. By this means, the shaft 9 is normally rotated from the'clutch member 12, but upon arrest of the printing membershafts A and B by means of the stop arm 13, the clutch'arin 21 willbe arrested, and the clutch blocks will slip on the rim 11 until the release of the printing members, when the clutch members will. at once grip and rotate the shaft 9.

The wristpins 18 and 19 are not rigidly se; cured to the'clutch member 12, but are normally loose therefrom, and a pawl and ratchet mechanism is provided for connecting these members upon the pawl being shifted by the operation of mechanism controlled by the arrest of the shaft A. The wrist pins are secured to a shaft 23 that is rotatable in a sleeve bearing member 24 projecting from an upright 25. The sleeve 24 forms a journal on which rotates the clutch member 12, a friction sleeve 26 being preferably fast on the sleeve 24. A retaining plate 27 is threaded on the reduced end 28 ofthe sleeve 24 and engages a shoulder portion 29 on the recessed mein the wrist. pin shaft around and cause actua" tion of the printing members. i -Meansare provided for shifting the pawl into engaging position upon the arrest of the shaft member 9, and when the wrist pin shaft has made a complete',-revolution, the oawl is thrown out of engagement with the ratchet shape of a ring,

wheel. A cam lever 34 in the asshown separatelyin Fig. 9, ispivoted on the plate 27, that is stationary on the bearing sleeve 24. This ring has a raised edge or peripheral portion 35, that normally engages the tailof the pawl 32, and holds its opposite end out of engagement with the ratchet of t eratchet 32, as shown in Fig. 5;

Wheel. The other edge portions of the cam ring are of less distance from the axis of the shaft 23. The cam ring can be rocked on its axis 36, and when moved inward, its engagortion 35 will no longer support the tail This will permit a suitable spring! to throw the ratchet outward to engage the'ratchet wheel.

The constantly rotating ratchet wheel will internal -nal radius is less than svsmo thereby carry the arm 33 and shaft 23 around. But the cam ring is normallyv having a nut 39 engaging the stop plate 27.

Upon the pawl approaching the end of a rev olution, its tail will engage a cam or inclined portion 40 that terminates in the said ele-. vated edge portion. 35; and the cam being returned to normal position, the pawl end will ride up this incline to the edge portion 35,

and thereby be swung 'out'of engagement with the ratchet wheel.

The cam ring34 is depressed by'rneans of a trip lever 41 on the arm 33. The arm 33 has a slotted portion 42 in which is pivotally mounted a block 43 The lever 41 is pivoted on thisblockand therefore has a swinging movement on the lever in the two directions at right angles. pin 44 having a beveled extremity 45, that in the normal position of the lever is in engagement with the face of cam ring 34, at a place 47 as shown in Fig. 4. When the lever 41, is in this position, and is moved inward, it will swing the cam leverand release the pawl, permitting the latter to engage the ratchet wheel. Should the lever 41 be held depressed, it would follow the cam ring around engaging therewith un til it reaches the hinged portion of the ring, the cam ring being now returned to its normal position by its spring. But after passing the hinge portion, the pin will move inside the ring because its diameter is here enlarged beyond the radial distance of the trip pin from the axis, at 46. The pin willthereupon ride its side of the cam ring at its enlarged portion. The stop pinis normally located opposite the portion 47 of the cam ring, where the interat the portion 46. This portion 47, is opposite the engaging portion 35 of the ring. Hence the inner face of the ring that engages the trip pin when in the depressed position must have an inwardly inclined portion 43 and the stop pin will be thereby moved radially inward at this tion. This'is permitted byreason of the ,stop pin having a swinging movement on its supporting block 43. Should the trip lever be pressed inward-and not released the completion of a revolution, the stop pin will ride inside the cam ring and remain in such position without again depressing the cam ring permitting the disengagement of. the pawl with the ratchet wheel by the incline The lever 41 carries a trip 40. If the stop'lever were released immedi ately upon disengaging the tail ofthe ratchet from the cam lever, as soon as the pawl ap cam lever to disengage the pawl.

tri will 4 tends to swin the pawl outwardly into enwardly gagement wit the ratchet wheel, and also tends to swing the lever 41 to move its stop pin away from the clutch axis. This spring will cause the pawl to engage the ratchet wheel as soon as it is released from the cam ring The spring will also swin the trip lever to move itsstop in outwar ly as soon as it is released after liaving moved inward from engagement with the inner face of the\ cam rin The trip lever 41 is moved out-,

om the face of the carrying arm 33 by means of a plate spring 51 and its move-' ment is limited by a stop 52, in both directions from the actions of said springs.

The trip lever 41 is actuated at each arrest of the printing members by the key lever stops, through a longitudinal movement given to the c utch member 10. In the resent construction, this is accomplishe by having the shaft member 9 formed in two parts, comprising a sleeve 55 that is secured to the spring piece 21 of the clutch member, and surrounds the extension 56 of the shaft A. The sleeve 55 has one or a pair of notches, one of which is shown in Figs. 1, 12 and 13. The notch has an incline surface 57. A sleeve 58 has a correspondingly inclined ortion 5 A coil spring 60 on the shaft 56 its extremities secured to the shaft and the sleeve respectively. The spring is, arranged to normally press the sleeve 55 against the sleeve 58 by its expansive tendj ency, and by its torsional construction it will tend to hold the two sleeves in the rotative position relatively in which shown in Fig. 1. But upon'arrest of the sleeve 58 by reason of stop arm 13 engaging a stop pin 15,

1 the continued rotation of clutch member 10 would tend to rotate the sleeve on the shaft 56, and hence rotate it relative to sleeve 58.

The engagement of the inclined faces 57 and 59 will cause an endwise advancement of the sleeve '55, advancing the clutch arm 21 to engage the trip pin 44 andoperate the clutch member as hcreinbefore set forth causing rotation of the wrist pins for one revolution only. This rotation of sleeve 55 will be arrested by reason of stop portion 61 coming into engagement with a stop portion 62 on the inclined face 59. lhereupon further rotatlon of the sleeve-55 is prevented, the

in guide-ways 80 and 81.

58, because the spring was put under torsional strain when the sleeve 55 advanced This will adupon arrest of the sleeve 58.

ositlon indicated vance the sleeve 58 to the in Fig. "13, in which the s eeves are in the same rotativeposition on the shaft, but the sleeve 55 has not been shifted axially upon the shaft to return it to its former shown in Fig. 1. Any'compression. that is put upon the spring 60 during the advancement of the sleeve 55 would tend to react and cause this axial movement. But this might be prevented by friction on the sleeve. To iosure the return of-the sleeve 55 to its forh er position, the notch in the sleeve 55 is provided with. another inclined face 86; and the sleeve 58 is rovided with asimilar inclined face 87. n the position in which the sleeves are shown in Fig. 13, the advance of the sleeve 58 by the torsional action of spring 60 will bring these inclined faces into engagement and it will be understood that this torsional action of the spring or reaction, will cause the engagement of these inclined faces to draw the sleeve 55 toward the sleeve 58, until the parts reach the position shown in osition as Fig. 1. This will return the clutch bar 10 to its former position and disengage the trip pin 44.

As shown in Fig. 11, connecting rods'70 and 71 are connected with the wrist pins 18 and 19 by boxes 72 and 73, which connecting rods serve to rock levers 74- and 75. These levers are. pivoted at 76 and 77 on the ma chine'frame, and their forward ends enga 0 slides in reciprocating bars 78 and 79 slidab e On the shaft A is secured a type wheel 82 having flexible ty e bars SScyhndrically disposed thereon. lowhr end, of the slide 79 engages the lowermost type bar when the wheel is arrested, and serves to press it downward. On the shaft B is secured a similar type wheel 84 having type bars 85, the up ermost of which,

when the wheel is arrester, is pressed upward by the slide 78. A printing plate in serted between theseiwo opposite type bars will be engaged by them onitsopposite sides ret ,iectivel y and the type on these bars being male and female respectively, will cooperate to p oduce a raised characterin the printing plate.
